fizz/67W f Cw To all who 2 it may concern:

Be it kn wn that I, JACOB F. BUPP, of Archbold, in th county of Fulton and State of Ohio, have inve ted certain Improvements in Well- Boring M chinery; and I do hereby declare that the llowing is a full, clear, and exact thereof, reference being had to the accompan ing drawing making a part of this specificat-i n, in which Figure .Plate 1, is a side elevation of the boring de ice, frame, and elevator. Fig. 2, Plate 1, is side view of the Windlass. Figs. 3, 4, and 5 are diiferent views of the boring device. i g. 6 is a perspective view of a portable supp t for the boring device. Fig. 7 is a sectional view of the shaft of the boring device with sweep attached to it. Fig. 8 is a sectional 'ew, showing the manner of connecting to ether the sections of the shaft of the boring evice.

tters of reference indicate corresponding n rts in the several figures.

The obj t of this invention is to provide certain de 'ces for boring wells, whereby the work can e performed with greater facility and with ss expenditure of manual labor than hithe o, as will be hereinafter explained.

The foll ing description of my invention will enable others skilled in the art to understand it.

In the represents companying drawing, Plate 1, A frame, which is strengthened by diagonal u aces a, and supported in an upright posit 11 upon long base-pieces, which may be s ked down to the ground in any suitable in nner. Below the topmost horizontal bea of the frame is another horizontal beam, which is scored at f and provided with a hor ontally-swinging clasp, e, which, with the s re, forms avertical box, which can be opened y swinging clasp e outward when it is necess ry for the coupling 01 to pass down below the cam, at which time another section can be ttached and confined by the clasp 0. These stain and guide the shaft of the boring dev e above the surface of the ground, and are arr nged high enough to allow a horse to walk aro nd below them. To the topmost beam of the ame A, and near the center thereof, a sheav B, is hung, over which passes a rope or cha I b, to which is attached a coupling-block, This rope or chain is used in PATENT QFFIGE.

withdrawing the boring-tool from the well, and also for raising and lowering a platform on which persons descend into the Well. From the sheave B the rope or chain bis carried under sheaves B and c, and thence to a windlass, as shown in Fig. 2, upon the drum of which it is wound.

The boring device consists of a circular plate, G, to which a shaft, D, is centrally secured, and through which a tube, i, passes,

for allowing an influx of air to the well below the plate G when the latter is being raised. There are two radial slots through the plate G diametrically opposite each other, which are provided with inclined cutters 1 which are about one-half the length of their respective slots, and so arranged that one cuts next the shaft 1) while the other cuts next the circumference of the circular plate G, so that they travel in different paths. Opposite each cutter or .bit 9 a plate, 9 is secured on top of the plate G, and made adjustable for the purpose of regulating the size of the throat through which the loosened earth passes from below the plate Gr to the surface above it. The cutters or bits are also adjustable for regulating the depth of out required. By means of a vertical cutting-fin, t, on the lower edge of the plate G, the sides of the well are cut down smoothly, and, by means of twisted blades 8 8 near the centering-point g, the earth which is loosened will be assisted in its passage through the throat in plate G.

When boring in quicksand the auger-plate G should be provided with a raised flange, indicated in Fig. 3 by dotted lines, which will retain within it the loose sand, and allow the same to be readily removed from the well.

The shaft of the anger is composed of sections of suitable length, connected together by means of coupling-boxes d and pins m, as shown in Fig. 8. The sections are made with flat sides. By means of such a shaft any desired depth can be given to the well by simply adding one section after another as the work progresses, and in withdrawing the auger from the well the sections can be successively re moved. To do this successfully I adopt the following devices: The sweep E has formed on it, near one end, two jaws, e 6 which receive between them the flat-sided shaft-sections. These jaws are perforated to receive a key, e as shown in Fig. 7. By this means the sweep E can be readily secured to and detached from any one of the shaft-sections D, and .the sweep can be maintained at a uniform height while the borer-shaft descends into the earth.

It will be observed that the shaft can be confined without being clamped tightly between the jaws e e and the key 6 Fig. 6 represents two strong planks, N N, which are jointed together by means of a staple, 0 p p, the prongs or spikes p of which are driven into the ground in proper relation to the well, so that when the two pieces N N are brought together, as shown by Fig. 6, they will lie over the well and receive, through a hole, a, the auger-shaft D. Now, as the couplingblocks d which connect the shaft-sections together are of larger diameter than the hole a between pieces N N, it will be seen that the auger can be readily supported by said pieces and blocks, and one section after another can be added to or removed from the auger-shaft.

To raise or lower the auger the rope b and Windlass are employed, and the block b is attached by a pin to the highest one of the coupling-blocks d. When a block, (1, rises above the surface of the ground the boards N N are brought together beneath it, and the section of shaft detached from it and also from the block b. The block b is then drawn down and attached to the block d, which is supported by the boards N. These latter are separated, and the work of raising the auger is again proceeded with. In this way one section after another is removed, until the anger is finally withdrawn from the well. Iii the same manner the shaft-sections can be added when lowering the auger into the well. The Windlass, its rope and block, together with a circular platform, are used for lowering persons into the well for curbing, or for any other purpose.

It will be seen from the above description that the beam A and clasp 0 guide and support the auger-shaft, while the horse which is hitched to the sweep E does the labor of boring. The jaws e and key 0 allow the sweep to be quickly adjusted on a section of the auger, or detached from, or attached tothe sections, as occasion requires; and by the same the sweep can be maintained at a uniform height while the augur is descending. The elevating-rope b, with its coupling-block b, and the Windlass enable me to perform all the work of raising and lowering the auger and other objects.

The swinging boards N, with the couplingblocks 01 of the auger-shaft, allow sections of this shaft to be added to and detached from it, and the said boards serve as a platform for supporting a loaded auger at the top of the well while the earth is being removed from it.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, 1s-

1. The shaft with the borer on its lower end, made in sectionsD D, coupled togther by means of boxes d d, the shaft and boxes being square or polygonal, and connected by pins, the boxes forming supporting-shoulders and liftin g-sockets, in combination with the lifting and lowering block b, substantially in the manner and for the purpose herein described.

2. The auger-plate, Gr provided with cutters g and adjustable throat plates g arranged substantially as described.

3. The feeders 8 combined with the auger, substantially as described.
